Setting parameter #6018 (D4) to “O” selects signals (M03, M04,
M05, M19, MF, FIN) instead of canned cycles (FMF, SSP, SRV) in
order to perform canned cycles. In spindle reverse by G74 and
G84, spindle can be stopped by setting parameter #6018 (D5) to
“l.”
Time chart is as follows.
Parameter #601 8 D5=0
M03 ++ M04
D5=0 M03 + M05 ++ M04
